中文摘要：

氧同位素组成是一个非常有效的示踪硫酸盐的起源和形成环境的工具。过去主要针对硫酸盐中的氧同位素δ（^18O）的研究，近年来，随着硫酸盐中氧同位素质量不相关分馏现象的陆续发现，其δ（^17O）的研究成为热．苣与前沿。在综述了硫酸盐三氧同位素测试技术的研究现状及进展情况后，重．苣介绍了从硫酸盐中直接提取O2供质谱计同时测定δ（^17O）与δ（^18O）值的CO2-激光氟化法；同时介绍了硫酸盐中氧同位素异常[△（^17O）]的研究历程，探讨了硫酸盐中氧同位素质量不相关分馏的机理及三氧同位素的应用前景，展望了今后的研究趋势。

英文摘要：

The composition of oxygen isotope is a good tool to trace the origin and formation environment of sulfate. In the past, the δ（^18 O） isotope was the main subject investigated, but now, the composition of δ（^17O） becomes the hotspots with the discovery of mass independent fractionation （MIF）to oxygen isotope in sulfate. The paper summarized the progresses in the research of the measurement technique of triple oxygen isotopes,and mainly introduced the method of CO2-laser fluorination. Meanwhile,it introduced the research course of oxygen isotope anomaly △（^17 O）,and discussed the mechanism and application foreground of MIF to oxygen isotope in sulfate,and pointed out the research tendency in the future.
